I Picked up a box of the 303 ammo a couple years back at a local car swapmeet and wondered if it was colectable myself as there is a few different types of it maybe some one here could shed a little light on it for me as I am a newbe on the 303. I have 4 different bullet types, round point (1917) pointy tip (1943) hollow tip (1943) and hollow tip with looks like a brass nail inserted into the hollow tip??? (1943). I also have a bunch of live blanks that are dated from 1915 to 1943, were they used fo training???. Any info would be great as they look interesting compared to alot of ammo I have seen.
